Question

two given A.P are 8,6,4,....and 24,21,18....if n th term of both the progression ate the equal than find the value of n​

Answer 1

Answer:

nth term of 1st Ap =

8+(n-1)(-2)

nth term of 2nd Ap=

24+(n-1)(-3)

Equating nth terms::

8+(n-1)(-2) = 24+(n-1)(-3)

-2n+2 = -3n+3 +16

n= 17

Therefore value of n is 17
